## Metrics Collection
|
|
|
|
### Application Metrics
|
|
|
|
#### Custom Metrics
|
|
```typescript
|
|
import { Counter, Histogram } from 'prom-client';
|
|
|
|
const requestCounter = new Counter({
|
|
name: 'http_requests_total',
|
|
help: 'Total HTTP requests',
|
|
labelNames: ['method', 'route', 'status'],
|
|
});
|
|
|
|
const requestDuration = new Histogram({
|
|
name: 'http_request_duration_seconds',
|
|
help: 'HTTP request duration',
|
|
labelNames: ['method', 'route'],
|
|
});
|
|
```
|
|
|
|
#### Business Metrics
|
|
- Transaction volume
|
|

|
## Dashboards
|
|
|
|
### Application Dashboard
|
|
|
|
**Key Panels**:
|
|
- Request rate
|
|
- Response times (p50, p95, p99)
|
|
- Error rates
|
|
- Active users
|
|
|
|
### Infrastructure Dashboard
|
|
|
|
**Key Panels**:
|
|
- Resource utilization
|
|
- Pod status
|
|
- Node health
|
|
- Network traffic
|
|
|
|
### Business Dashboard
|
|
|
|
**Key Panels**:
|
|
- Transaction volume
|
|
- Revenue metrics
|
|
- User activity
|
|
- Conversion rates

## Alerting Rules
|
|
|
|
### Critical Alerts
|
|
|
|
```yaml
|
|
groups:
|
|
- name: critical
|
|
rules:
|
|
- alert: HighErrorRate
|
|
expr: rate(http_requests_total{status=~"5.."}[5m]) > 0.1
|
|
for: 5m
|
|
labels:
|
|
severity: critical
|
|
annotations:
|
|
summary: "High error rate detected"
|
|
|
|
- alert: ServiceDown
|
|
expr: up{job="api"} == 0
|
|
for: 1m
|
|
labels:
|
|
severity: critical
|
|
annotations:
|
|
summary: "Service is down"
|
|
```
|
|
|
|
### Warning Alerts
|
|
|
|
```yaml
|
|
- alert: HighLatency
|
|
expr: histogram_quantile(0.95, http_request_duration_seconds) > 1
|
|
for: 10m
|
|
labels:
|
|
severity: warning
|
|
annotations:
|
|
summary: "High latency detected"
|
|
```
|
|
|

|
|
|
|
## Log Aggregation
|
|
|
|
### Structured Logging
|
|
|
|
```typescript
|
|
import winston from 'winston';
|
|
|
|
const logger = winston.createLogger({
|
|
format: winston.format.json(),
|
|
transports: [
|
|
new winston.transports.Console(),
|
|
],
|
|
});
|
|
|
|
logger.info('Request processed', {
|
|
method: 'GET',
|
|
path: '/api/users',
|
|
status: 200,
|
|
duration: 45,
|
|
userId: '123',
|
|
});
|
|
```
|
|
|
|
### Log Levels
|
|
- **ERROR**: Errors requiring attention
|
|
- **WARN**: Warnings
|
|
- **INFO**: Informational messages
|
|
- **DEBUG**: Debug information
|
|
|

|
## Distributed Tracing
|
|
|
|
### OpenTelemetry
|
|
|
|
```typescript
|
|
import { trace } from '@opentelemetry/api';
|
|
|
|
const tracer = trace.getTracer('my-service');
|
|
|
|
const span = tracer.startSpan('process-request');
|
|
try {
|
|
// Process request
|
|
span.setStatus({ code: SpanStatusCode.OK });
|
|
} catch (error) {
|
|
span.setStatus({ code: SpanStatusCode.ERROR });
|
|
span.recordException(error);
|
|
} finally {
|
|
span.end();
|
|
}
|
|
```
|
|

## Best Practices
|
|
|
|
### Metrics
|
|
- Use consistent naming
|
|
- Include relevant labels
|
|
- Avoid high cardinality
|
|
- Document metrics
|
|
|
|
### Alerts
|
|
- Set appropriate thresholds
|
|
- Avoid alert fatigue
|
|
- Use alert grouping
|
|
- Test alert delivery
|
|
|
|
### Logs
|
|
- Use structured logging
|
|
- Include correlation IDs
|
|
- Don't log sensitive data
|
|
- Set appropriate levels
